Application filed September23, 1927. Serial No. 222,468;

The invention concerns accounting machines and has for its principalobJect the provision of mechanism for adaptlng a machine operatingaccording to one system of mathematical progression to another systemand to furthermore provide simple and novel mechanism for this purposenecessitating fewer and less radical changes in thecontrol and datareceiving devices than have heretofor been required. An equallyimportant object of the invention is to provide such mechanism ofunivversal application capable ofadapting each data receiving unit-to asingle denominational order regardless of whether the increment ofprogression is greater or less than that for which the controlsandreceiving devices are normally designed. For example the usual.accounting machine normally operates according to a decimal system andmay be modi fied to operate according to fractions in certain ordersprovided the fractional denominators are less than ten. If it is desiredto operate in certain orders according to fractions whose denominatorsare greater than ten V8,: rious expcdiencies'have been resorted to, suchas using several entering units for thesingle fractional order. It isoften very convenient to adapt one denominational order to twelve forhandling the English monetary system or inches and feet and owing to theimportance of this fraction in accounting machine practice it will beselected to illustrate the method of practicing the invention. 7

' Another object of'the invention is to provide mechanism for adaptinganaccounting machine normally operating'according to a decimal system tooperate according to frac- .tions' in certain orders without ntroducing'lost motion connections.

Another object of the invention isto provide mechanism for recordcontrolled raccounting machines to permit record cards having normallyspaced index point positions to control machine operation in such manneras they would if the index point positions were spaced closer togetheron the cards, that is to substantially contract the index point s acingwith respect to machine operation.

Now ifinstead of ten index point positions the card is provided with twelvespaced as'before and the type bar is provided withtwelve type spacedcloser together on the bar so that they pass through printing positionin the same time as the ten formerly did, it is obvious that theanalysis of the card and the movement of the type bar. no longer agree.The contracting feature of the invention provides for maintainingsynchronous motion between the card feed and the type bar andcompensating for the in- I crease in the length of the analyzing operation due to the extra index points.

- Another object ofthe invention is to provide mechanism for recordcontrolled accounting machines to -permit record cards :havmg normallyspaced index points to control machine operation in such manner as theywould if the index points were spaced further apart on the cards, thatis to substant-lally expand the index point spacing -with respecttomachine operation. This is substantially the reverse of thecontractingoperation.- For example, only eight index point positionsmight be used on a card 001- Y umn and eight corresponding. type locatedon atype bar covering the same space that ten normally covered. Tomaintain synchronous motion between the card and typebar inthis case theincrease of type. spacing on thebar must be compensated. f A

Another object of the invention is'to provide for rearrangement of theindex points on a controlling record for entry into'ithe accountingmechanism of the machine. I The usual single hole control card-isprovided Flirts 1 f James W. BRYCE, or ntoonrrntnnnw JERSEY, assrenon TDrun TABULATING Ma- "in a twelve point system the machine would have tobe arranged to transpose the entering order so that the effect on theaccounting mechanism would be the same as if the index point positionswere arranged on the card in the order 11, 10, 9, 8,7, 6, 5, 4, 3, 2, 1,0. This transposition is provided for in the present invention.

Another object of the invention is to provide translating mechanism for"effecting the above translations consisting of a reading-in commutatorcooperating with the analyzing mechanism to effect setups from which thetranslated data may be entered into the accounting mechanism.

AnOtherobJect of the invention is to provide setup mechanism for theabove translation consisting of a commutator with brushes shiftabletransversely thereof.

Another object of the invention is to provide translating mechanism forthe above translation in which each shiftable brush is provided with anindividual shifting magnet.

Another object of the invention is to provide translating mechanism forthe above translations in which entries are received from a controllingcard during one machine cycle and the translated data are entered intothe accounting mechanism during a subsequent'machine cycle.

The invention will be described, by. way of example, in'connection witha specific form of record controlled printing tabulator. The tabulatoris controlled by record cards on which numerical data may be representedby index points or perforations placed in any one of ten differentiallylocated index point positions in each card column, a single index pointin a column representing a particular digit, according to its location.The cards are fed with a continuous motion one each machine cycle,beneath analyzing brushes of which there is one for each card column, so

that the brushes search the index point positions successively. Thedriving mechanism of the adding devices and the driving mechanism of theprinting devices operate synchronously with the card feed. A magnet isconnected to each analyzing brush for con: trolling one denominationalorder of the adding mechanism and an operating pulse through this magnetresults in coupling the adding device to its driving mechanism, thecoupling persisting until a predetermined point in the machine cyclewhen it is automatically released. The pulses from the analyzing brushthen momentarily energize the magnet in accordance with the'location ofthe index points and effect entry of the digits digit represented by thelocation of the perforation on the card in printing position. Both theprinting and adding mechanisms are thus controlled by current impulsesdifferentially timed during the machine cycles.

According to what is at present believed to be the preferred form of theinvention the contraction, expansion or transposition, as

the case may be, is efi'ected through an auxiliary mechanism interposedbetween the analyzing brush and the adding or printing magnet. As a cardis fed beneath the analyzin brushes the current pulses resulting from inex points, instead of acting directly upon the adding or printingmagnets to enter the data, act upon the intermediate auxiliary mechanismto effect setups corresponding to the locations of the index points onthe card.

During the following machine cycle after the card is entirely clear ofthe analyzing mechanism the set up is reconverted into a timed currentimpulse for operating the adding or printing magnet. The auxiliarymechanism, owever, has provisions for retiming the impulses so that theyoccur in the proper order and with the proper timing to operate theadding and printing mechanism according to the required expansion,contraction or transposition.

. I The intermediate auxiliary mechanism. of

which one is provided for each card column, may consist generally of twocommutator devices, one of which will hereinafter be re ferred toas thereading-in commutator and the other as the reading-out commutator. Thereading-in commutator rotates synchronously with the card feed and has aseries of contacts on its periphery arranged in groups equal in numberto the active index point positions on the card. The groups are spacedto engage brushes riding on the commutator surface as the analyzingbrush passes the several index point positions on the card and thecommutator contacts are electrically connected to the analyzing brush.When the latter encounters a perforation a combination of circuits isclosed through the particular group of commutator contacts then underthe commutator brushes and these combinations are different for eachindex point.

- The reading-out commutator is rotated synchronously with the drivingmechanisms of the adding and printing devices. In the present case ithas been assumed that these mechanisms operate synchronously with thecard feedas they ordinarily would in machines of this type'but, ofcourse, this is not essential and they might have a different type ofmovement altogether. The readingout commutator is provided with aplurality of brushes shiftable transversely of its surface, each of.which may selectively engage one of two circumferential rows of contactson the commutator surface. The brushes are shifted by individual magnetsconnected in l the circuits extending through the reading-in commutatorbrushes and the analyzing brush, from which it will be understood thatacertain combination of brushes are shifted for each index pointencountered by the analyzing brush. The circumferential rows of contactson the reading-out commutator are likewise arranged in transverse groupsequal in number to the different characters which might be entered intothe adding and printing mechanisms. These transverse groups i arearranged to complete circuits through the shiftable brushes and theadding and printing magnets at certain times in the machine cycleaccording to the particular combinations of brushes which have beenshifted. Obviously the contact groups may becarranged to initiateimpulses timed as desired with respect to the machine cycle and therequired expansions, contraction and transpositions are thus providedfor.

The invention is shown in Fig. 14 as a plied to a Wellknown type oftabulator fully described in the copending application of Daly and Page,ruary 5, 1925 (now Patent No. 1,762,145, issued June 10, 1930). Thetabulator is represented diagrammatically and its circuit dia- Ser1alNo.6980, filed Febgram and general operation will be explained volved intabulating and listing operations are driven by the tabulating motor TMwhile the total taking mechanism and the printing? devices in totalprintin operations are driven by the reset motor Rfi. Before starting atabulating operation the machine must be driven through a reset cycle toclear the accumulators of any data which mi 'ht remain in them from aprevious tabulating operation and also to prepare the circuits of thetabulating motor for operation. The reset cycle is started by depressingthe reset key R closing a circuitthrough the reset motor RM from oneside of the main line 21 through resetmotor RM, reset clutch magnet 22,contacts 23 and normally closed listing contacts L--2 to binding post 12in the other side of the main line 26. Immediately after starting thecam contactsP-1 close shortcircuiting the reset clutch magnet 22 topermit the reset clutch to disengage at the end of the cycle,

and the reset motor itself is stopped at the end of'the cycle by theopening of these contacts. This reset cycle momentarily closes andthenopens the lower contacts P--3 there;

by'energizing motor control relay 84 in seriesv with its stick magnet91. The stick magnet prepares an additional circuit throu h cam areclosed, the tabuing motor to binding post 16, thence through the cardfeed-clutch magnet 25 and start key contacts ST, motor relay contacts86, through stop key contacts S to bindingpost 9 and through uppercontacts P+3 closed except lating motor may be started by depressingthe.

The tabulating motor TM and the card feedclutch magnet remain in operation through their various circuits, whichneed not be described in detail, as long as the contacts86 of the motorcontrol relay 84 remain closed.

. The card feed clutch magnet 25 when energized causes engagement of thecard feed clutch which through suitable picker mecha- 'nism indicated at27 causes the cards 28 in the ma azine of the machine to feed one at atime beneath the upper analyzing brushes 30 and the lower analyzingbrushes 31, one

card feeding beneath the upper brushes during one card cycle and beneaththe lower tion. These contacts are normally open but are closed whenevertheir controlling mag nets 36 are energized and when closed remaln sountil after the contacts 0-1 have opened and closed during the machinecycle The upper brushes 3O cooperate w1th contact blocks 37 which areconnected to soclrets 38 The lower brushes 31 through similar 3 contactblocks 39 are connected to sockets 40.

It will be understood that although only two upper and two lower brushesare shown in the drawings, any number of them to operate on any numberof card columns, the usual commerc al machine containing 45 upper and 45lower brushes. Certain of the card columns are chosen for group controldata and the group control magnets 36 are connected in series throughthe sockets 38 and 40 with the corresponding upper and lower brushes. Aslong as the control perforations in the control columns of the cardsunder the upper and lower brushes during a card cycle agree, the magnets36 are energized at some time during the cycle closing their contactsand establishing a shunt about cam contacts O1. The machine thereuponremains in operation for another card cycle. As soon as the controlperforations in the-cards under the upper and lower brushes fail toagree, indicating the end of a card group the control magnets 36 fail toenergize, control contacts 35 remain .open andthe opening of camcontacts. C1 during the cycle causes deenergization of the motor relay84 permitting contacts 86 to, open interrupting the normal operatingcircuit of the the machine may be provided with the order 9, 8, 7,

thence through wires 41 and 42 to lower card lever contacts LG, closedas-long as cards are passing the lower brushes, thence through wire 43to cam contacts T'2 and T3 and through wire 44 to the lower brushes 31.The cam contacts T 2 and T-3 open and close to permit energization ofthe lower brushes only when the data can ing portion of the cardis'passing the lower rushes. As the cards passthe lower brushes theirindex perforations permit the lower brushes 31 to instantaneously engagetheir cooperating contact blocks 39 to continue the brush circuits tothe sockets which may be plugged to the usual adding and printin devicesof the machine. The left hand rush 39' is shown so plugged to a countermagnet 164 for controlling it in the usual manner according to a decimalsystem.- The differentially timed impulses resulting from-the indexpoints serve to energize magnet 164' at differential times during thecycle to operatethe adding and printing mechanism of the machine in amanner well understood.- a

In the present case the right hand upper brush 30 is shown connectedwith translating mechanism according to the present invention to read a.certain card column' for twelfths instead of tenths and to modify theeffect of the entering impulses. The reason for using an upper insteadof a lower analyzing brush for this purpose will appear later. Thegeneral scheme of operation of this translating mechanism will beexplained in connection with a system for adding twclfths on certainaccumulators and printin elements 1n amachlne operating normal yaccording to the decimal system.

Referring to Fig. 5 a controlling card of the Hollerith type is shown atH provided with index point positions in columns for the digits fromnine to zero with two extraindex point positions after the zero,designated as ten and eleven.

brushes coverlthe lndex point positions'in of the machine is shown inFig. 8 and this bar rises synchronously with the passa e of the cardpast the analyzing brushes to ring its 6, 5, etc. A normal type but Theanalyzing type opposite the printing line 45 as the cor respondlng indexpoint positions on the card are passing the analyzing brushes. If theadding mechanism operates in a similar manner except that the impulseresults in clutching the counter elements to their driving shaft for adefinite time in the cycle corresponding to the index point which causesthe impulse. Referring again to Fig. 5, if it is desired to operate themachine in certain columns according to twelfths instead of tenths, thetwo upper index point positions .10 and 11 may be used but this resultsin lengthening the analyzing portion of the cy cle and also indisplacing the 10 and 11 index points from their logical progressivepositions on the card; that is, instead of being analyzed prior to-the 9index point position they are analyzed after the zero index pointposition. In Fig. 9 a type bar 50 is shown with twelve type designatedfrom zero to eleven spaced within the same spacing as the ten type onthe normal type bar 48 in Fig. 8, and in order to make the machinestandard as far as possible, it is necessary that the type bar 50 movesynchronously with the other decimal type bars 48 of the machine. To

operate this type bar (see Fig. 5) it is necessary not only to compressthe longer analyzing cycle into one of normal length but also torearrange the order of the index points as indicated at T. If this isdone, the printing magnet 51 in Fig. 9 will be operated to trip thelatch 52 permitting it to engage the several teeth 53 on the type bar toarrest the type on this bar in the proper position for printing.

The general manner in which this compressing and transposition isefiected may be understood from Fig.14. This right hand upperanalyzingbrush 30 controls the twelfths printing and counter magnetsthrough intermediate translating mechanism'which in the present caseconsists of a reading-in commutator 55 and two pails of reading-outcommutators 56 and 57. The analyzing brush is connected to abrush 46making contact with a continuous conducting strip 47 on the reading-incommutator. The reading-in commutator is driven in synchronism with thecard feed'making only one half a revolution, however, for each cardfeeding cycle. Two sets of brushes 59 and 60 cooperate with a group ofcontacts 61 on the commutator surface. The contacts cover substantiallyhalf of the periphery and coact with the brushes 59 during one cardfeeding or machine cycle and with the brushes 60 during the followingmachine cycle. The brushes 59 control magnets 62 and the contacts 61 arearranged so that a certain group of them' is under the brushes whenacertam index point is under the analyzing brush thereby energizing themagnets 62 in different combinations for each index point on the cards.The brushes 60control similar magnets 63 during alternate cycles in anidentical manner. The two pairs of reading-out. commutators 56 and 57are operative during alternate cycles and are provided with shiftablebrushes which are shifted under control of the magnets '62 cooperatingwith the brushes of the commutators 56 and magnets 63 cooperating withbrushes of commutators 57. The shiftable brushes cooperate with contactson the surface of reading-out commutator to retime and rearrange theentering impulses from which the counter magnet 64- is energized at thedesired time to enter the data which is recorded onthe'cards. The datais read from the card during one cycle and the magnets 62 energized toshift the brushes on the commutators 56 and during the following cyclewhen the succeeding card is under the analyzing brushes thecommutators56 cooperate with the brushes as shifted to energize thecounter magnet 64 at the proper time during the cycle. Duringthisfollowing cycle the contacts 61 cooperate with the brushes 60 toenergize the magnets 63 for shifting the brushes on the commutators 57and the data from this card is entered into the counter magnet duringthe next following cycle. The operation of contracting and transposingdata entries may be best understood from Fig. 2 of the drawings in whichthe reading-in and reading-out commutators are shown in development. Thecontacts 61 on the readin -in commutator surface are ar j ranged in ourcircumferential rows indicat-f ed at A, B, C, and D, each rowcooperating with an individual brush 59. The contacts are also arrangedin transverse rows desig-. nated as 9, 8, 7, 6,5, 4, 3, 2, 1,0, 10 and11, each transverse row except the one designated 0 containing one ormore contacts. Themotion of the commutator is such that the row marked 9is under the brushes 59 when the 9 index point position on the card ispassing the analyzing brush and so on. Whenever the analyzing brushencounters a perforation a certain combination of the magnets 62 isenergized to shift corresponding brushes 65 on the reading-outcommutators 56.

The reading-out commutators are likewise each provided with fourcircumferential rows of contacts 66 arranged also in transverse rowsdesignated as 11, 10, 9, 8, 7, etc. Each brush 65 normally cooperateswith one circumferential row of contacts 66 but when its Y magnet 62 isenergized is shifted to cooperate with an adjacent row. The upper brush65 of the upper commutator 56 is connected 9 is connected in accordancewith an index point one of the transverse rows of contacts 66simultaneouscorresponding 1y bridges the two pairs of brushes at a givenpoint in the cycle resulting in an entering impulse through the countermagnet. The timing and order of this entering impulse depends, ofcourse, on the arrangement of contacts 66 in transverse rows andobviously the order and timing can be arranged in any desired manner. Itwill be noted that the transverse rows of contacts 66 are spaced closertogether than the transverse rows of contacts 61 which accounts for thecontracting feature. The arrangement of the contacts in rows providesalso for the transposition of the 10, 11 impulses to their proper placein the series.

The operation will be clearer from a specific example. Assume that anindex point occurs in the 6 index point position of a card under theupper brush. As this index point encounters the analyzing brush acircuit will be completed through the brush 46 and conducting strip 47to the contacts 61 in the 6 row, that is in the A and D circumferentialrows. Owing to the synchronous movement of the card and commutator, the6 rowis at this time under the brushes 59 and the circuit is extended intwo branches, one leading to the magnet 62 designated A and theotherleading to the magnet 62 designated D thereby energizing thesemagnets'to shift their brushes 65 on the reading-out commutators 56.After the shifting is complete the upper brush 65 cooperates with thesecond circumferential row on the upper commutator 56 and the lowerbrush 65 on the lower commutator cooperates with the lowercircumferential row of contacts 66 on this commutator. As a 6 is to beentered into the accounting and printing mechanism, indicating in thepresent case six twelfths, it will be noted that no circuit can becompleted through the contacts 66 until the transverse row 6 comes underthe shiftable brushes 65..

At this time each pair of brushes 65 will be bridged simultaneously bythe connected contacts in the row and the resulting'ope'r ating impulseo erates the counter and printing magnets.

trol the shiftable brushes 65 to initiate an entering impulse at theproper time in the following card cycle. It'will be understood that thepulses initiated from index-points in the right hand column of the cardshown in Fig. 5 have thus been rearranged and spaced closer together asindicated by the points 11, 10, 9., 8, 7, 6, 5, etc. designated T.

ther index points on the rec- 0rd card operate in a similar manner tocon-' trains 7 0, one gear of which is freely mounted on the countershaft 71. The counter shaft rotates during adding cycles but the geartrains 70 do not rotate until they are positively clutched to the shaft.The clutching mechanism comprises clutch teeth on the side of the gearof train 70 which is mounted onthe shaft and sleeve members 72 which aresplined to the shaft but shiftable in and out of engagement with theclutch teeth on the gear. The clutching engagement is effected bymomentary energi'zation of the counter magnet 64. This magnet isprovided with a pivoted armature 73 which carries a latch for pivotedlever 74. This lever has one end extending into an annular groove in theclutch sleeve 72 and its other end spring-pressed by one of the springcontacts urging it to clutching position, from which it is normallymaintained, however, by the latch on armature structure 7 3. When themagnet 64 is energized to attract its armature the latch is releasedpermitting the lever 74 under action of the spring contact 75 to forcethe clutch sleeve 72 into engagement with the conforms ,to thedifferential timing of the impulse which energized magnet 64.

The translator mechanisms indicated generally at 80 of which'one isprovided for each card column in which a translation is to be. I

made are driven 'insynchron'ism with the counter shaft71 througha geartrain 81 having a gear ratio to cause the reading-in and reading-outcommutators tomake one revolution for each two card cycles or every tworevolutions of counter shaft 71. The operating elements of thetranslators 80 are driven from gears 82 fixed to a shaft 83 which isdriven by the gear train 81. It may be assumed that the lower counterwheel 69 is arranged to indicate twelfths while the others are arrangedto indicate tenths. The driving connection between the twelfths counter'wheel 69 and theshaft. 71 is similar to that for driving the othercounter wheels in that it comprises a constantly meshed gear train and.a similar clutching element. Either the gear train or the gear teethfor this twelfths unit must be arranged so that the counter wheel mayrotate in increments of twelfths instead of tenths- The complete drivingcycles of all the counter elements coincide. however, and the twelveincrements of movement of-the lower counter wheel may occur. ".withinthe same elapsed time as the ten more-- ments of'movement of the, othercounter wheels: The difierent timing of the entering 5 impulses for'thejtw'elfths unit are spaced within the normal entering cycle as justex type bar carrying ten type with-normal spac ing is provided with ninenotches 85 to permit arresting the type bar in any of the nine 35positions represented by the type one to nine. I In Fig. 9 the type bar50 carries twelve type from zero to eleven which-are so spaced on thebar as to cover the same distance as the ten type on the bar 58 do, andthe bar is provided 2 with eleven notches 53 to permit arresting themotion of thetype bar with any of the I type from one to eleven inprinting position upon the line 45. The cyclical operation of theprinting is notdisturbed and the type -bars i8 and 50, rise together tobring their type opposite the printing line. The type bar 48, however,may be controlled directly from an analyzing brush while the type bar 50in order to compensate for its contracted type spacing must becontrolled through a translating device, the entering impulses beingretimed' and rearranged'as j u'st explained;

The printing magnet 51 is controlled from a. the counter magnet '64during listing operations "(see Fig. Whenever the magnet 64 is energizedduring a tabulating operation it efi'ects closure ofcontacts 88 therebycompletinga circuit through the printing magnet 51; the closure of thiscircuit being substantially simultaneous with theentering impulsethrough the counter magnet so that the same data ma be entered into theadding units and printed.

9 At the end'of a card group as previously I i stated, the tabulatingmechanism ceases op-' eration anda total may thereafter bev taken eitherautomatically or by the pressing of reset button R. It will be recalledthat the translating mechanism is set up during one card cycle and thereading, as modified, en-

ter'ed into the accounting mechanism during the following card cycle;This is the reason that the upper instead of the lower analyzing brusheshave been used to control the readgroup is followed in the presentmachine by a totaling cycle and if it were attempted to control thetranslating mechanism from the lower brushes the data from the last cardof each group would remain in the translating mechanism over the totaltaking operation and would be entered into the accounting mechanismsduring the first tabulating cycle of the following group. Controllingthe w from the upper brushes,,howe ver, the

; entry injgin mechanism. The last card cycle of 'a data from the lastcard is entered into the translator when the last card is passing theupper brushes and is read out as the last card is passing the lowerbrushes during the last tabulating cycle of the group.

The total taking clrcuit through theiprinting magnet 51 extends throughcontacts 90 whose operation is clearer from Fig. 4. This figure showstotal taking mechanism associated with the counters which is fullydescribed in the copending application of Lake Serial No. 639,193 filedMay 5, 1923. A gear 93 constantly meshes with the train 7 0 to ro- -tatewhenever the counter wheeli69 rotates.

Fast to this gcarv93 is a stepped cam 92 havcording to the tens systemof progression, it would be provided with nine steps corresponding tothe digits from one to nine while if operating according to the twelfthssystem of progression, it would be provided with eleven stepscorresponding with the numbers from one to eleven. Durlng the totaltaking operation the type bars move uniformly as before through printingposition and syn chronously'with this movement a shaft 95 'rocks. Fastto this shaft is a frame 96 on which is pivoted a contact finger 97carrying a set screw 98 at its end, cooperating with the 1 steps of cam92. The finger 98 is held by a spring 99 in the position shown in'thedrawings against the frame 96 and it is provided with an arcuate rearextension 100 which is energized during the total taking cycle, from abrush 101 fixed on the machine frame and sliding on the arcuate surfaceof 100. The

frame 96 carries a brush 102 which when the V finger 97 is in normalposition against the frame is just clear of the arcuate extension 100.The frame and finger rock downward as the type bars rise until the setscrew 98 encounters one of the ste s' on cam 92 whereupon the movementof nger 97 is arrested and the continuing motion of frame 96 causes thebrush 162 to engage the arcuate extension 100 and thus initiate anentering impulse for the printing magnet. The position of the cam 92alwa s corresponds to the number indicated bythe adding wheel 69and theimpulse initiated 'is therefore 'diiferentially timed during the cycleaccording to the numbers standing on the accumulator so that the Iproper type 18 selected for printing.

The structural details of the translating mechanism are shown in Figs.1, (land 7'. In Fig. 1 a complete translating unit is Shawn consistingof one reading-in commutator 55 and two sets-of reading-outcommutatorsefi.

and 57. These commutators together with their operating magnets 62 and63 are mounted on a common base plate 165'. The

performs two cycles, thecommutators each make one revolution. Thecommutators 56 and 57 with their brush shifting and other operatingmechanisms are identical and only one set will be described. Theconstruction of the reading-out commutators will be most clearlyunderstood from Figs. 6 and? of which Fig. 7 shows the parts in normalpo- 110 on the pivoted supporting structure of:

the armature 111 of shifting magnet 63. When the magnet 63 isdeenergized the lever 108 is held in the position shown in Fig. 7 by theextension 110 overlying the extension 109. When the magnet is energizedto attract its armature as shown in Fig. 6 the ex-- tension 110 movesofi the extension 109 and permits the spring 113 to shift the lever 108bringing the brush 65 into the position shown in Fig. 6. The commutator57 is cut away for substantially half its periphery and this cut awayportion is opposite the brushes 65 during that card cycle in whichshifting impulses through the magnet 63 occur. Refer ring to Fig. 1itwill be noted that the cut away portions of the reading-in commutators56 and 57 are displaced 180 degrees "with respect to their shiftablebrushes so that the brushes of one set of commutators may be freely setup during one machine cycle while the brushes of the other arereading-out an entry; The brushes'65 either in their shifted orunshifted position ride in grooves 112 in the raised portion of thereading-out commutators. These grooves serve to insulate the ends of thebrushes from each other and the contacts 66 are placed at the bottom ofthem. Shortly after the brushes 65 leave the grooves 112 any of themwhich have been shifted to-take'a reading are shifted back to the normalposition in.Fig.,7. A pivoted arm 115 is provided with a pin 116 whichextends into the path of a cam 117 mounted on the face of the drivinggear of the commutator. This cam encountering the pin rocks the arm 115whose end thereupon restores the lever 108 to normal position allowingthe extension 110 on the supporting structure of armature 111 to againengage the projection 109 on' lever 108 and hold it in this normalposition until the magnet 62 is The invention thus far has beenexplained in connection with a device for adapting a twelve pointprogressive system to a ten point machine but it is obvious that it 515equally well adapted to other systems. In Fi s. 10 to 13 a translatingmechanism is indicatedfor operating in accordance with an eight pointprogressive system for han dling eights fractions. In this case thecounter mechanism and the printing mechanism for handling eights movessynchronously with the usual tensmechanisms performing a complete cyclein increments of eights. In this case if the usual card indicated at Hin Fig. 11 is utilized for indicating eighths only seven index pointsfrom zero to seven will be utilized and it will be neces sary to expandthis portion of the analyzing cycle to cover a complete normal analyzingcycle as indicated. Here the spacing of the entering impulses must beexpanded instead of contracted. In Figs. 12 and 13 a normal type bar 48hearing ten type is aligned with a type bar 51 hearing eight type fromzero to seven covering the same'space longitudinally of the bar as theten type on bar 48.

The type bars as before rise synchronously and the retiming of theentering impulses according to Fig. 11 serve to compensate the differentspacing on the eights type bar. In the case of the accumulatingmechanism the drive for the eights counter wheel must, of

course, be adjusted to provide for increments of eight-hs instead oftenths.

The developments of the reading-in and reading-out 'commutators for theeighths transformation is illustrated in Fig. 10. The reading-incommutator 55" is identical with the reading-in commutator 55 exceptthat the transverse rows of contacts corresponding to'the index points9, 8, 10 and 11 have been omitted leaving only the rows from one toseven corresponding to index point positions in which perforations maybe placed. -The reading-out commutators 56 rotate as before insynchronism with the counter driving mechanism and the printingmechanism but as in this case entering impulses may occur only in sevendifferent positions only seven rows of transverse contacts 65' areprovided, these seven rows being evenly spaced within the same spacethat the eleven rows occupied on the twelfths readingout commutator's.Aside from this different spacing of the contacts on the reading-outcommutators the operation of the machine is identical with thatexplained in connection with the twelfths system. An index point on acontrolling record in the column representing eighths result in shiftingof certain brushes 65' and the contacts 66 are arranged in transverserows so that the entering impulses are retimed as required to cover thecomplete normal entering and analyzing cycle.

The invention has now been described in connection with severalembodiments to illustrate generally its distinctive features. It is tobe, understood, however, that these embodiments have been selectedmerely with a view to illustrating the utility of the device and are notto be construed in a limiting sense. The. transpositions, that is therearranging of the timing of the pulses resulting from index points, isof general application. If desired tWo spaces in the middle part of thecard for example the index points 5 and 6 might be left blank and theseindex points displaced to the 11 and 12 positions and transposed back totheir proper position for entry by the transposing mechanism.
